Hi Mina,

This error relates to the CalDav protocol of your calendar. As IMAP works well according to the log you uploaded, it seems that there is a problem on the server’s side during the handshake with eM Client. Please contact your mail server’s provider for a possible solution or a fix of CalDav server settings.
